## Abstract

A battery module includes an array body in which a plurality of battery cells are arranged, a plurality of harnesses extending in an array direction of the battery cells in the array body and having connecting terminals of tips connected to electrode terminals of the predetermined battery cells, and a binding member configured to bind the plurality of harnesses in a harness bundle, wherein the harnesses branched off from the binding member have flexure between a position at which the harnesses are bound by the binding member and connecting positions of the electrode terminals and the connecting terminals.

## Claims

### Claim 1

A battery module comprising:
an array body in which a plurality of battery cells are arranged;
a plurality of harnesses extending in an array direction of the battery cells in the array body and having connecting terminals of tips connected to electrode terminals of the predetermined battery cells; and
a binding member configured to bind the plurality of harnesses in a harness bundle,
wherein the harnesses branched off from the binding member have flexure between a position at which the harnesses are bound by the binding member and connecting positions of the electrode terminals and the connecting terminals.

### Claim 2 (depends on 1)

The battery module according to claim 1, further comprising:
an elastic body disposed at one array end of the battery cells in the array body, wherein
the plurality of harnesses are pulled toward the array body from the one array end side at which the elastic body is disposed, and
the position at which the harnesses are bound by the binding member is disposed closer to the elastic body than the connecting position of the electrode terminal and the connecting terminal.

### Claim 3 (depends on 2)

The battery module according to claim 2, wherein
the position at which the harnesses are bound by the binding member is disposed closer to the elastic body than the connecting position between the electrode terminal and the connecting terminal when the battery cells of the connection destinations expand.

### Claim 4 (depends on 2)

The battery module according to claim 2, wherein
a flexure amount of the harness branched off from the binding member is increased when the battery cell to which the corresponding harness is connected is disposed closer to the elastic body.

### Claim 5 (depends on 1)

The battery module according to claim 1, wherein
a mark showing the position at which the harnesses are bound by the binding member is formed at each of the harnesses.

### Claim 6 (depends on 1)

The battery module according to claim 1, wherein
the harnesses are harnesses used to detect a voltage of the battery cell.

### Claim 7 (depends on 2)

The battery module according to claim 2, further comprising:
a retaining member configured to restrict the array body in the array direction via the elastic body.
